Answer:
V₂ = 150 mL
Explanation:
Given data:
Initial volume of sample = 250 mL
Initial pressure = 450 mmHg (450 /760 = 0.6 atm)
Final pressure = standard = 1 atm
Final volume = ?
Solution:
The given problem will be solved through the Boly's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
0.6 atm × 250 mL = 1 atm × V₂
150 atm. mL = 1 atm × V₂
V₂ = 150 atm. mL/ 1 atm
V₂ = 150 mL
Answer:
B
Explanation:
A. Is wrong
This definition in this option does not fully define what an open system entails. It only gave a one sided definition of the phenomenon on ground
B is correct
In an open system, matter and energy should be free to leave
C is incorrect
This is clearly a one sided definition like A and should not be taken serious
D is incorrect
D is talking essentially about what a closed system is
Hope the diagram below will help you. when a C=C is hydrogenated it gains 2 hydrogens turning it into a C-C.
Hope that helps
